I The object of my presentinvent-ionis the- "provision of a simple;

inexpensive and effi-,. cient fender for street cars andother vehicles,and one which will perform the desired :func:

tion of picking up a person in the path of a 7 car or other vehiclewithout .injuri11g such person;

qfTo the attainment ofthe foregoing, the

invention consists in the improvement as 7 as extended and ready foruse. f

"hereinafter described and'definitely clairnedg. "In the" accompanyingdrawings, forming V j part hereof:-..
